DXX-Rebirth fails to build

For future reference, which part of the code shows libraspberrypi-dev as missing?

You're confusing code with the log output. The only error I see in the 'scons.log' is

g++ -c -g -O2 -ftabstop=4 -Wall -Werror=extra -Werror=format=2 -Werror=missing-braces -Werror=missing-include-dirs -Werror=uninitialized -Werror=undef -Werror=pointer-arith -Werror=cast-qual -Werror=missing-declarations -Werror=redundant-decls -Werror=vla -pthread -funsigned-char -O2 -march=armv8-a+crc -mtune=cortex-a53 -mfpu=neon-fp-armv8 -mfloat-abi=hard -ftree-vectorize -funsafe-math-optimizations -Werror -Wno-sign-compare -isystem=/opt/vc/include -isystem=/opt/vc/include/interface/vcos/pthreads -isystem=/opt/vc/include/interface/vmcs_host/linux -DPHYSFS_DEPRECATED= -DRPI -Icommon/include -Icommon/main -I. .sconf_temp/conftest_0.cpp -o .sconf_temp/conftest_0.o

On a Stretch system, those folders belongs to the the package I mentioned (which is installed by default by RetroPie).

$ dpkg -S /opt/vc/include/interface/vcos/pthreads
libraspberrypi-dev: /opt/vc/include/interface/vcos/pthreads

It's the same on Buster, maybe try re-installing the package ?

redman223

I ran: sudo get-apt install --reinstall libraspberrypi-dev

Still the same issue. I'll keep an eye out for Buster comparability updates.

@redman223 I tested it now. It installs fine. It auto installed the required dependencies and then it compiled without issues. I'm using a pi4 with raspbian lite buster. Maybe update the retropie pi4 branch?

redman223

@Darksavior By that do you mean I should go into Retropie-Setup and run Update?

Darksavior

@redman223 Update raspbian buster as well. I don't know how retropie updates work with alternate branches, so just in case, I'd re-clone the github fkms_rpi4 branch and try again. Make sure you clean the dxx-rebirth source folder if it gives you the option before building again. I did not do anything special to build it. The script should auto-download the required dependencies.

redman223

@Darksavior So I ran:
sudo apt-get update
sudo apt-get upgrade

In addition to Update from within RetroPie-Setup.

It still does the same thing. Any next steps for troubleshooting?

@redman223 It never failed to build for me so I don’t know. I also never manually installed missing libs.

This is a build error related to the new gcc version in buster. I'm going to send a fix upstream.

Darksavior

@psyke83 Funny how mine built fine then?

It's a problem that crops up only if you build against the legacy drivers. If you've got a Pi 4B or are using the fkms overlay for older, the problem won't happen.

I tried it again today and can confirm that it now installs properly. Thanks for the help!
